The parties agree that\nCTI will provide 180 Staff Months of employee service over the two year term of\nthis agreement.\n\n     Although each Loaned Employee shall at all times remain an employee of CTI,\nhe or she will perform duties and be under the general direction of CNC for the\nterm of this Agreement, or until such Loaned Employee's assignment is otherwise\nterminated as provided in Section 3 hereof.

Because of this, it\n          is in the best interests of both CTI and CNC that the employees be\n          treated in as equivalent a fashion as possible with respect to\n          compensation, benefits, and working hours\/rules. CTI and CNC agree to\n          develop an appropriate employee transition plan upon hiring by CNC of\n          any St. Louis based Network Operations loaned employees to achieve\n          these objectives.\n\n          (b)  Loaned Employees who will be made available to CNC will be\navailable only after they have executed Letters of Agreement in the form\nattached hereto as Exhibit B, which form the parties hereto expressly approve.\n\n          (c)  The parties hereby acknowledge and agree that Intellectual\nProperty Rights, as defined in Exhibit C, created, written, developed or made by\neach Loaned Employee while performing services for CNC pursuant to this\nAgreement shall be subject to the addendum to the Loaned Employee Letter of\nAgreement (Exhibit B).\n\n          (d)  In addition to the other terms and conditions of this contract,\nCTI and CNC agree and stipulate, as further consideration for the promises made\nby each party hereunder, as follows:\n\n               (1) CTI will use its best efforts to ensure the successful and\ntimely implementation of the Intuit contract.

If the Option is not assumed, the\n                    provision shall require the surviving or acquiring entity to\n                    pay to the respective optionees, in cash, or in the form of\n                    stock of the acquiring or surviving entity, an amount equal\n                    to the amount which the total, vested shares of CNC stock\n                    held by all optionees hereunder represent in relation to the\n                    total price paid for CNC by any acquiring or surviving\n                    entity on the date CNC is acquired, merges with another\n                    entity, or undergoes a change in control or ownership.  To\n                    illustrate, all parties agree that the following example\n                    accurately expresses the intention of this provision in the\n                    event the Options are not assumed:\n\n     In the event CNC is acquired by, or merges with another entity, and the\n     total price paid by the acquiring or surviving entity to obtain CNC,\n     considering all forms of compensation, is \"X', and further considering that\n     all the vested stock options of CNC held by all optionees hereunder on the\n     date of the acquisition or merger is \"Y\", and further considering that if\n     \"Y\" represents \"Z\" percentage of the total value of all stock of CNC which\n     is valued at \"X\", then the acquiring or surviving entity shall pay to the\n     optionees hereunder an amount equal to \"Z\" of the purchase price of CNC\n     (\"X\"), in amounts as directed by CTI. Said payment shall be in the form of\n     stock of the acquiring or surviving entity or in the form of cash, said\n     form of payment to be chosen by the acquiring or surviving entity. If stock\n     is chosen as a method of payment, said stock shall\n\n                                      -12-\n\n \n     be Class A common stock with no restrictions on the sale or transfer of\n     said stock whatsoever other than restrictions which would apply to all\n     shareholders of CNC receiving stock in the merger.\n\n     Said provision, as illustrated above, shall be a part of any acquisition or\nmerger contract with any acquiring or surviving entity entered into by CNC.\nFurthermore, CTI shall have the right to review the terms of said provision\nprior to the execution of the acquisition or merger contract by CNC.\n\n                    (5) Attached hereto as Schedule I and incorporated herein by\n                    reference are certain additional covenants and agreements of\n                    the parties with respect to the grant and exercise of\n                    Options hereunder.\n\n          (iii) Representation Concerning Capital Structure of CNC,\n                ---------------------------------------------------\nFinancial Statements.

In the event a Loaned\nEmployee shall become a CNC employee as provided hereunder, any time said\nemployee spends during the term of this contract working for CNC toward the\ngoals of CNC under this contract shall be counted as \"staff months\" in favor of\nCTI in calculating the \"Staff Months\" pursuant to Section l(a) of this contract.\nAdditionally, all time spent by Shelley Mortimer, Timothy Hood, and Tony Zeis\ntoward the goals of this contract shall also be counted toward the \"Staff\nMonths\" regardless of the fact that said persons are employees of CNC.\n\n               (b) If an Optionee becomes an employee of CNC, his or her Options\nshall continue to vest according to the terms herein.\n\n     If the employee later returns to the employment of CTI during the term of\nthis contract, the previous change in employment status shall not affect the\nvesting rights of that employee with respect to the Options, and he or she shall\nbe treated as if he or she had never left CTI's employ for stock vesting\npurposes.\n\n                                      -14-\n\n \n     7.

Compliance with SEC Rule 504.  CNC agrees that it will take all<br \/>\n          &#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;-<br \/>\nreasonable steps to comply with Rule 504 of Regulation D (&#8220;Regulation D&#8221;)<br \/>\npromulgated by the Securities and Exchange Commission (&#8220;SEC&#8221;) under the<br \/>\nSecurities Act of 1933 (the &#8220;Act&#8221;) so long as CNC is not subject to the<br \/>\nreporting requirements of Section 13 or 15(d) of the Securities Exchange Act of<br \/>\n1934 (the &#8220;Exchange Act&#8221;).  These steps will include, but not be limited to:<\/p>\n<p>          a.   CNC will timely file a notice on Form D with the SEC.<\/p>\n<p>          b.

CNC will bear the expenses of registration of such Shares other<br \/>\n     than underwriters&#8217; discounts and commissions with respect thereto, and fees<br \/>\n     and expenses of counsel to the selling shareholders.<\/p>\n<p>          b.   Such selling shareholders will execute the Underwriting Agreement<br \/>\n     pursuant to which Shares are sold in the registered offering, which<br \/>\n     Underwriting Agreement may contain indemnification and other provisions in<br \/>\n     substantially the form normally contained in such agreements.<\/p>\n<p>                                      -2-<\/p>\n<p>          c.

Please indicate your<br \/>\nconcurrence with these modifications by signing below.  The specific changes for<br \/>\nour &#8220;Employee Service and Staffing Agreement&#8221; are:<\/p>\n<p>1)    Delete paragraph 1d, subsections 4 and 5.<\/p>\n<p>2)    Waive the notice of an extension in paragraph 2.0 and extend the agreement<br \/>\n      for an additional two (2) years (October 31, 1999).<\/p>\n<p>3)    Change section 4f (second paragraph) so that the upcharge Is changed to<br \/>\n      [*] instead of [*] for staff positions currently on board as of the<br \/>\n      signing of the agreement (see attached listing). Change the upcharge to be<br \/>\n      only on base salaries, payroll taxes and benefits. Other expenses<br \/>\n      associated with hiring will be passed through at cost. Said taxes and<br \/>\n      benefits are currently billed at [*] of base salaries; therefore, the<br \/>\n      total markup over base salaries is [*]. Additional hiring over those<br \/>\n      positions noted on the attached list will be at a [*] upcharge or<br \/>\n      currently [*] over base salaries. Additionally, CNC commits to a<br \/>\n      minimum level of staffing equal to the staffing level as of the date of<br \/>\n      signing of this document.<\/p>\n<p>4)    Delete paragraph 6(a).<\/p>\n<p>5)    Delete 8(a)(4) and change 8(a)(3) so that said fees are no longer due<br \/>\n      unless sites are added after Installation of the super POPs currently<br \/>\n      scheduled.<\/p>\n<p>6)    As a consideration of this agreement, the CNC board must agree that all<br \/>\n      &#8220;performance shares&#8221; or options have been earned (see attached<br \/>\n      &#8220;Performance Summary&#8221;).

Said option agreement to<br \/>\n      be provided within 10 days of the board meeting following the signing of<br \/>\n      this agreement. Failure of the CNC board to approve these two items will<br \/>\n      nullify this agreement.<\/p>\n<p>7)    It is agreed that paragraph 10 of the existing contract shall provide that<br \/>\n      CTI shall have the right to assign or transfer their duties, obligations<br \/>\n      and all benefits under the contract to a merger or acquiring entity so<br \/>\n      long as that entity is not Netcom, PSI, UUNET, ANS, ATT Worldcom, MFB,<br \/>\n      GTE, Ameritech, PAC Bell, SBC, US West, NYNEX, BellSouth, Bell Atlantic,<br \/>\n      Sprint Internet\/Intranet Services, MCI Internet\/Intranet Services, and<br \/>\n      CompuServe Network Services. Should CTI be acquired by one of the named<br \/>\n      competitors, CNC may at Its option exercise the &#8220;buy out option&#8221; and pay<br \/>\n      CTI a cash payment equal to [*] of the remaining value (an a present<br \/>\n      value basis at prime) of its profit and any unpaid relocation expenses<br \/>\n      (see &#8220;e&#8221; below). Said option to be exercised with ninety (90) days of<br \/>\n      notice by CTI of intention to merge with a competitor of CNC.<\/p>\n<p>8)    CTI further agrees to limit access to CNC proprietary information to only<br \/>\n      those CTI employees who have a need to know.<\/p>\n<p>9)    In order to provide an orderly transition at the end of the agreement, CTI<br \/>\n      agrees to locate all personnel and resources used to support CNC to a new<br \/>\n      subsidiary and transfer that entity to CNC according to the following<br \/>\n      plan:<\/p>\n<p>      a.    CTI will create a wholly owned subsidiary. CTI will transfer all<br \/>\n            existing CNC staff to this entity. Additionally, all new CNC related<br \/>\n            staff will be hired by this subsidiary for those CNC operations<br \/>\n            housed in St. Louis, Missouri.<\/p>\n<p>      b.    CTI will transfer its rights (including leasehold improvements)<br \/>\n            under Its lease to 3324 Hollenberg Drive to this new subsidiary.<br \/>\n            Said lease to have at least five (5 years remaining at the<br \/>\n            termination of this agreement at a cost not to exceed [*] per<br \/>\n            square foot (triple net). Any office equipment currently owned by<br \/>\n            CTI and used exclusively by the subsidiary employees will also be<br \/>\n            transferred. Additional office equipment for current or future<br \/>\n            employees of the subsidiary will be paid for by CNC and remain their<br \/>\n            assets.<\/p>\n<p>      c.    CTI will transfer a nonexclusive license to its software for network<br \/>\n            modeling, site management. and telco reconciliation to this new<br \/>\n            entity.<\/p>\n<p>&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;-<\/p>\n<p>     [*]Certain information on this page has been omitted and filed separately<br \/>\nwith the Securities and Exchange Commission.  Confidential treatment has been<br \/>\nrequested with respect to the omitted portions.<\/p>\n<p>      d.    CNC shall acquire title to this new subsidiary at the and of this<br \/>\n            agreement and CTI will vacate the promise on 3324 Hollenberg Drive.<br \/>\n            Both parties agree to execute such documents as may be necessary to<br \/>\n            minimize the tax effect to both entities.<\/p>\n<p>      e.    CNC shall pay CTI [*] for relocation expense and the assets of<br \/>\n            the new subsidiary. This amount will be paid for costs as needed by<br \/>\n            CTI to relocate its other business to other facilities. CTI will<br \/>\n            provide to CNC on at least a quarterly basis their projected needs<br \/>\n            for the next six months. All of these funds could be paid in advance<br \/>\n            of the completion of this agreement. Any funds not so advanced will<br \/>\n            be paid at the point where ownership of the subsidiary transfers to<br \/>\n            CNC.<\/p>\n<p>      f.    CTI agrees to reimburse CNC an amount equal to 35% of the annual<br \/>\n            salary of any CNC employee (acquired through the acquisition of the<br \/>\n            subside&#8221;) that returns to CTI or its other subsidiaries within one<br \/>\n            year of said acquisition.<\/p>\n<p>      g.    CTI agrees to use its best efforts to ensure that all employees of<br \/>\n            the subsidiary stay with the entity when the transfer to CNC occurs.<\/p>\n<p>10)   Sections 4 and 7 shall be modified to require joint agreement by both CTI<br \/>\n      and CNC on all matters relating to the hiring and compensation of the<br \/>\n      employees employed by the subsidiary.<\/p>\n<p>11)   In the event CNC determines that it requires additional local access POP<br \/>\n      locations, before CNC executes an agreement with any other person to<br \/>\n      provide such locations to CNC, CTI will negotiate for a period of thirty<br \/>\n      (30) days with CNC for CTI to provide such locations. In the event that<br \/>\n      CTI and CNC are unable to reach agreement within such 30 days, CNC shall<br \/>\n      thereafter be free to execute an agreement with any other person to<br \/>\n      provide such locations to CNC so long as the terms of such agreement when<br \/>\n      considered in the aggregate (including such matters as price, facilities,<br \/>\n      response times and other relevant factors bearing on the overall value of<br \/>\n      such an arrangement to CNC), are no more favorable to such other person<br \/>\n      that the most favorable terms offered by CNC in writing to CTI during such<br \/>\n      30 days of negotiation.<\/p>\n<p>12)   CTI agrees to provide other consulting services to CNC at a rate not to<br \/>\n      exceed the lowest offered by CTI to other customers requiring similar<br \/>\n      services (including duration or quantity of such services).<\/p>\n<p>&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;-<\/p>\n<p>      [*] Certain information on this page has been omitted and filed separately<br \/>\nwith the Securities and Exchange Commission.
